Jetronic fuel-injection systems have proved their worth in millions of cases sińce they were introduced. The continu-ous further development of the control unit and the sensor have led from the D-Jetronic to the L-Jetronic and madę this fuel-injection system morę precise and morę reliable. New Circuit variations in the evaluation of the sensor signals have led to morę economical and morę com-fortable operating qualities of the engine. Thanks to the use of the Lambda sensor and the Lambda closed-loop control inte-grated into the control unit, the L-Jetro-nic can already fulfill the exhaust-gas requirements of tomorrow. This booklet tells you all you need to know about the latest developments in L-Jetronic.
